Would appreciate advice on whether there are any foreseeable problems in driving a pair of 4 ohm rated DynAudios from a Denon AVR2310. I have been running them as a 2 channel system off a Yamaha A-S700 but I am considering adding a DynAudio center speaker and hooking up to the Denon as a 3 speaker system. Getting mixed responses as to overheating and music quality issue. Very small listening area and rare to take things up past about 30% of capability. I have another set of DynAudio Excite 12 speakers (also rated as 4ohm) as an option. All comments most appreciated. (PS: should have added the Denon VR is rated at 6-16ohm).
